LF Schechter parameters, LF absolute magnitude bias limits, LDs, SFRDs and dust attenuation derived from our rest-frame FUV-150 LF estimates in 10 redshift bins from z = 0.05 to z = 4.5 assuming (Ω_m, Ω_Λ, h) = (0.3, 0.7, 0.7).

Notes. Values derived for the merged VVDS Deep+Ultra-Deep sample at 17.50 ≤ I_AB ≤ 24.75. There is no Ultra-Deep data at z < 0.2.

^(a)

Redshift bins.

^(b)

Schechter parameters (M^∗, α and φ^∗) of our VVDS rest-frame FUV-150 luminosity function that we use throughout this work.

^(c)

Absolute magnitude limit in FUV down to which the survey is complete is terms of galaxy types (see Sect. 3.1), for the Deep and the Ultra-Deep surveys, respectively.

^(d)

Rest-frame FUV luminosity density uncorrected for dust. The quoted uncertainty includes errors on the LD induced by the STY LF fit, the Poisson noise, the cosmic variance, and the weighting scheme. When α is set at z > 1.7, the STY errors include also the percentage uncertainty accounting for the two extreme values of α (−1.1, −1.73) with respect to those quoted in the third column (see text). The relative contribution of each source of error is detailed in Table 2.

^(e)

Star formation rate density uncorrected for dust, derived from the rest-frame FUV luminosity density. For the errors see note (d).

^(f)

Average dust attenuation in FUV.

^(g)

Star formation rate density corrected for the dust attenuation A_FUV. For the errors see note (d).
